Igor, I would say I've never noticed this, but I just pulled out the FA50/1.4. I've used it on A all the time, and the first turn away was just as you described. I felt like I was forcing it. The click stops were not so much clicks as potholes. It felt like it was really banging around. It seemed a bit lighter toward wide open, but bad at f22. Still, I don't have any problem with it, but it's certainly not like the F lenses. Regards, Bob S.
